ALKA LI PHENOLATES OI ORTHOGXYMERCUR'IC SALICYLIC ANHYDRID.

To all whom it may concern: a

Be it known that we, \VALTER SCHOELLER and WALTHER SGHRAUTH, doctors of philosophy, chemists, citizens of the German Emplre, residing at Berlin, Germany, have invented new and useful Improvements in Alkali Phenolates Salicylic Anhydrid, of which the following is a specification. I

Our present invention relates to the preparation of the hitherto unknown alkali phenolates of the ortho-oxymercuric salicylic anhydrids of the formula:

li c naonjwoo (ll/l standing for an alkali metal).

For producing the products of the above given formula the solution of the known ortho-oxymercuric salicylic anhydrid (hydrargyrum salicylicum of the German Phawnacojoaeia) of the formula:

IlIg c n on f coo in one molecular proportion of caustic alkali lye is evaporated in vacuo. The products of the above given formula separate out. They can also be precipitated from the concentrated solution either by the addition of suitable agents e. 9. methyl alcohol, acetone, etc., or any other similar method. The new compounds thus obtained are slightly colored odorless compounds which are very easily soluble in water and insoluble in ether. The sodium salt is insoluble in methyl alcohol, the corresponding calciumnot precipitate albumen that is to say that Specification of Letters Patent.

of I Orthooxymercuric Patented Aug. 16, 1910.

Application-filed May 20, 1909. Serial No. 497,302. (Specimens.)

they are not irritant and that themercury contained therein does not blacken surgical instruments.

In order to illustrate our new. process the following example is given, the parts being by weight: 20 parts of the ortho-oxymercuric compound of-sali'cylic anhydrid (hydrargyrum salicylicum) (one molecular proportion) are dissolved in an aqueous solution of 2.38 parts of NaOH. The resulting solution is-filtered and the filtrate is evaporated.

in mono, A slightly colored crystalline compound separates with an almost theoretical yield. On analysis the compound is found to have the formula; 7

containing 55.97 per cent. of mercury. The same salt is obtalned by adding methyl alcohol to the concentrated solution of one molecular proportion "gof the hydrargyrum salicylium in a solution of one molecular proportion of NaOH.

' We claim:

1. The herein described new alkali phenolates of orthooxymercuric salicylic anhydrid of the above given formula obtainable .from the ortho-oxymercuric compound of salicylic anhydrid, which are slightly colored compounds easily soluble in Water and insoluble in ether and in methyl alcoholf which do not precipitate albumen; and are valuable therapeutic compounds, substantially as descri-bed.

2. The herein described new sodium phenolate-of ortho-oxymercuric salicylic anhy- 'drid of the above given formula, obtainable from the ortho-oxymercuric compound of salicylic anhydrid, which is a slightly colored crystalline compound easily soluble in water and insoluble in ether; insoluble in methyl alcohol; and isa valuable therapeutic compound, substantially as described.

In testimony whereof we have hereunto" set our hands in the presence of two subscribing witnesses.
